The 4Cs
Carat weight, colour, clarity and, for round brilliants, cut grade describe the centre stone. Fluorescence, polish and symmetry can also be relevant.

Start with the right question
A diamond ring is a stone, a setting and sometimes a signature.
The value of a diamond ring depends on more than the size of its centre stone. The quality of that stone, the metal and design of the mount, any accompanying diamonds, the condition of claws and shank, and whether the ring was made by a recognised house such as Tiffany & Co., Cartier, Graff, Harry Winston or De Beers all shape how it is received by resale buyers.
EncoreLuxe reviews certified and uncertified diamond rings privately from anywhere in the UK. You can begin with photographs and whatever paperwork you have. The initial review is complimentary, EncoreLuxe buys outright rather than lending against jewellery, and every offer is subject to physical examination, stone testing and authentication of any signature.
Practical framework
The details that matter most
Grading report
A report from a recognised laboratory such as GIA, IGI or HRD Antwerp records the stone’s characteristics and can be matched to a laser inscription.
Setting and metal
Platinum, 18ct gold, claw, bezel, halo or three-stone designs, shoulder stones and the condition of claws and shank are all assessed.
House signature
Signed rings from established jewellers are considered for collection, signature, serial number and original documentation.
Certified and uncertified diamonds
A grading report from GIA, IGI or HRD Antwerp gives a buyer an independent starting point: the report number, carat weight, colour and clarity grades, measurements and, often, a plotted diagram of inclusions. Many reports correspond to a microscopic inscription on the girdle of the stone. If you have a report, photograph every page and keep the original safe; we will check that the stone matches it during the physical review.
Many excellent rings have no certificate, particularly older and inherited pieces. That is not a barrier to selling. Without a report, the stone is assessed in hand for its characteristics and tested to confirm it is a natural diamond. It is helpful to tell us anything you know, such as a retailer’s description or an old insurance schedule, but please do not have a stone removed from its setting before enquiring.
Settings, shoulders and condition
The mount is more than a holder. A well-made platinum or 18ct gold setting from a respected maker supports the appeal of the whole ring, while a thin, resized or heavily repaired shank may need attention from a future buyer. Worn claws, loose stones, chipped edges and missing accent diamonds are all recorded honestly, and none automatically prevents a purchase.
Photograph the ring from above, from each side, and at the inside of the band, where the hallmark and any maker’s mark or size stamp usually sit. A short note on resizing, re-tipping of claws or replacement stones is useful. UK hallmarks indicate metal fineness, for example 950 for platinum or 750 for 18ct gold, and help confirm the construction of the mount.
Signed rings from recognised houses
Rings by Tiffany & Co., Cartier, Graff, Harry Winston and De Beers are made to recognisable house standards and usually carry signatures and serial numbers. Many are sold with a house diamond certificate, a pouch and box, and a receipt. When these details align with the ring itself, buyers have more confidence, and that confidence is reflected in how a signed ring is assessed.
Signatures alone do not prove authenticity. Counterfeit engravings exist, and some genuine house mounts have been re-set with stones that did not originate with the brand. EncoreLuxe therefore considers the signature, serial format, construction and stone together, and compares any documents with what is physically present before an offer is confirmed.
Laboratory-grown stones and what to disclose
Laboratory-grown diamonds are chemically diamond but form a separate market from natural stones. If a ring contains a laboratory-grown centre stone, or you are unsure, please say so. Reports for laboratory-grown stones state their origin, and many are inscribed accordingly. EncoreLuxe will explain whether a particular ring is suitable for purchase after review.
Disclose any treatments you are aware of as well, such as clarity enhancement or colour treatment, along with past repairs. Clear information at the outset saves time and avoids an initial indication changing once the stone is examined in person.
Questions, answered
Before you
send it in.
Do I need a GIA or IGI certificate to sell my diamond ring?
No. A report is helpful, but many rings are sold without one. The stone is examined and tested in hand during the physical review.
Should I remove the diamond from the setting?
No. Please leave the ring as it is. Removing a stone risks damage and can make a signed or well-made mount harder to assess.
Do you buy signed Tiffany or Cartier diamond rings?
Yes. Signed rings from recognised houses, including Tiffany & Co., Cartier, Graff, Harry Winston and De Beers, can be submitted with any box, certificate and receipt.
Is an insurance valuation the same as a selling price?
No. An insurance valuation usually reflects the cost of replacing the ring new at retail, which is a different basis from a direct resale offer.
Can you tell me what my ring is worth from photos?
Photographs support an initial indication only. Any offer is confirmed after physical examination, stone testing and authentication, and you can decline without obligation.
